Cover the multilayer film. It can be covered by double or multi-layer insulation film, or it can be covered with shed or covered mulch in the shed, or covered with non-woven fabric. Ningbo Kyson Cool Electronic Technology Co., Ltd. , https://www.kysonrefrigeration.com
Add a second floor curtain. The inner side of the shed is provided with insulation materials such as straw curtains and reed mats to thicken the buffer layer between the air outside the shed and enhance the insulation capacity of the greenhouse.
Burning furnace. During the cold wave, use a heating furnace with a smoke exhaust pipe to warm up. It should be noted that the exhaust pipe should be tight to prevent leakage of smoke and cause damage to vegetables.
Smoked smoke increases temperature. This method increases the temperature quickly and better. In an acre shed, use 2-3 tiles to install sawdust in the shed to ignite the smoke and cold, or pile up firewood or charcoal on the greenhouse walkway to warm up, pay attention to the fire can not be too large, so as not to burn the surrounding plants. At the same time, we must guard against fires.
Install a warming bulb. In an acre shed, install 25-30 warming fill lights, and each day and night to open an anti-freeze effect.
In addition, the use of electric heating line to warm, increase the application of warm organic fertilizer can also increase soil temperature to prevent freezing of vegetables. However, the laying of the heating wire heating method can only be used for the seed tray nursery shed, and the cost is high, and it is not recommended to use it in a large area.
Nowadays, the technology is more and more developed, and there are more and more temporary warming measures, such as increasing the air heating line, electric furnace wire, heater, iodine tungsten lamp, incandescent lamp, LED energy-saving lamp, reflective film and Other facilities. In the emergency warming and filling light, the effect is very good.
